Abstract

This paper describes a highly integrated MMIC frequency discriminator (3.3 mm/spl times/5.5 mm) for S-band. The discriminator consists of two balanced mixers, three Wilkinson power dividers (one of them has integrated a 90/spl deg/ phase shifting network) and one amplifier. To ensure a certain frequency resolution, several discriminators with different delay lines have to be connected into a parallel configuration. An integrated amplifier enables distributed amplification and reduces the specifications for the driving limiting amplifier. The high performance achieved and the small die size makes this discriminator suitable for integration into IFM systems.<>
